Title: Waste paper sticky contaminants magnetic elimination.
Inventor: MARWAH NIPUN
Filed: 1997-04-23
Abstract: The present invention describes an improved process to eliminate waste paper "sticky contaminants" containing adhesives and hot-fusion and pressure-sensitive latices, to produce high quality pulp (with high brilliance, and low or no dirty content), with low or no fiber lost. Process involves joining waste paper pulp sticky particles to a magnetic carrying material with the help of a binding agent, followed by joined sticky particles elimination by magnetic separation. Magnetic treatment is preferably performed at room temperature or higher, in a pH from neutral to alkaline, and a low pulp consistency. Binding and magnetite addition, followed by re-pulped waste paper exposition to a magnetic field, provide an almost complete sticky contaminants elimination, by being exposed to magnetic field without such previous treatment. Invention most representative figure is the number 1.
